Answer 2

Thank you everyone . i have found another way of adding IDENTITY property without sql commands.

In SQL Server Management console , go to Object Explorer->Select your Database->Select your Table->Right click on the Column on which Identity property has to be specified->Choose Modify option. In column Poperties window , scroll to Identity Specification . Change value of IsIdentity to Yes and specify seed and increment values and save.
